Srinidhi commented on SHIRO-821:
--------------------------------
Hi [~bdemers], yes that is correct. The patterns are part of legacy config and
some of them contain trailing spaces (that cannot be easily updated), and the
URLs are coming from other applications (which are also not in our control).
Can you please share the PR as part of which the original bug was corrected?

> Key: SHIRO-821

> Issue Type: Bug
> Affects Versions: 1.7.1
> Reporter: Srinidhi
> Priority: Major

> Hi,
> Not sure if this is a bug but there appears to be a difference in the
> way regex patterns with trailing spaces are matched in shiro-core. This
> behavior seems to have changed between v1.7.0 and v1.7.1.
> Steps to replicate:
> RegexTest.java:
> {code:java}
> import org.apache.shiro.util.AntPathMatcher;
> public class RegexTest {
> public static void main(String[] args)
> {
> AntPathMatcher matcher = new AntPathMatcher();
> System.out.println("Matching ====" + "/a/b/* " + "==== with ====" +
> "/a/b/c" + "====");
> System.out.println("RESULT: " + matcher.match("/a/b/* ", "/a/b/c"));
> }
> }
> {code}
>
>
> Output with v1.7.0:
> $ java -cp "shiro-core-1.7.0.jar;." RegexTest
> Matching ====/a/b/* ==== with ====/a/b/c====
> RESULT: *true*
>
> Output with v1.7.1:
> $ java -cp "shiro-core-1.7.1.jar;." RegexTest
> Matching ====/a/b/* ==== with ====/a/b/c====
> RESULT: *false*
>
> Can you please let me know if this change was an intentional fix to an
> existing bug or a new bug that got introduced?
> Is there any flag to retain the prior behavior?
>
> -Thanks
